A committee picks its own name. Its funders are on a form.

01

Four kinds of committee, and why they are never ranked together

A governor’s campaign and a fire-levy committee are both committees. Sort them into one table by money and you get a list in which the levy never appears, and in which a $2,400 cheque and a $2.1M cheque sit in the same column meaning entirely different things. Washington governs the classes differently, so the register keeps them apart and explains each before you filter into it.

Candidate committees

One per candidate per race, dissolved after it. Contributions are capped — $2,400 per giver for statewide office, $1,300 for legislative — so no single funder can dominate one, and the largest-funder column is close to meaningless here by design.

Ballot measure committees

No contribution limits at all. One company or one union may lawfully fund an entire campaign. This is where the largest-funder column does its work, and where the biggest single numbers in the archive live.

Continuing political committees

PACs that persist between cycles, raising from members or donors and giving onward. Uncapped on the way in, capped on the way out when they give to a candidate. Most of the money in this archive passes through one of these.

Party committees

State, county and legislative-district party organisations, plus the caucus campaign committees. They operate under their own limits and exemptions, which is why a party committee’s numbers should never be compared to a PAC’s.

The register

Alphabetical by default, as everywhere on this site. Raised and spent are separate columns and are never netted — a committee that raised $6.2M and spent $6.0M has not “made” $200,000, it has $200,000 left.

Largest single funder

The biggest itemised contribution from one giver across the cycle — not a controlling interest and not ownership. Where a committee reports only aggregated small giving, the cell says that instead of naming someone. The share is the one division we perform, and both operands are printed.

Status

The design carries a status column — active, dormant or dissolved, from the last filing. The registration status field is empty for every committee in the PDC extract we hold, so the column is absent rather than filled with a guess. A dissolved committee stays in this directory permanently either way; deleting spent committees would make every past cycle look smaller than it was.

Class

A measure committee is one that filed a ballot number or a for/against stance — mechanical, from the registration. The design for this page imagines candidate, PAC and party as further classes; our extract of the register does not carry them, and deriving them from the name a committee chose for itself would put our judgement in a column that looks like a filing. So those classes are absent rather than guessed.

Where most of the money came from one place

4 committees in this cycle drew more than half their itemised money from a single giver. Both columns are quoted from filings — the left from the registration, the right from the contribution reports. We put them side by side and add nothing.

What this directory will not compute

Committee data is the easiest data on this site to make lie, because every plausible sum of it has a name that sounds like journalism. This block is on the directory rather than on every committee page, because it is a fact about the corpus rather than about any committee in it.

A donor’s grand total

Money given to a PAC that gives to a candidate would be counted twice, once at each hop, and the result would exceed the money that exists. Each contribution is shown at the hop it was filed at, and no page adds across hops.

Committee families

Two committees with a shared treasurer, a shared address or similar names are not one organisation, and merging them into a “network” total is the single most common error in this field. Affiliation is published only where a committee declared it on its own C-1.

Whether a name is misleading

That is a judgement about intent. The directory prints the name and the largest funder at equal weight, in every row, for every committee — including the ones whose names and funders agree perfectly — so the treatment is a format rather than an accusation.

Whether the money worked

No page here divides money by votes. A committee that spent in fourteen races and saw nine of its preferred candidates win did not thereby cause those outcomes.

A single ranking across classes

A governor’s campaign and a fire-levy committee are both committees, and sorting them into one money-ordered table produces a list in which the levy never appears. Classes are governed differently; the filter keeps them apart.

Netting raised against spent

The difference between raised and spent is cash on hand, not profit or virtue. The two columns stay separate and no column subtracts them.

A “dark money” list

Washington has no separate registration for a committee that only runs independent expenditures — it is an ordinary committee that files C-6 reports. So that is a flag on a row here, not a list with an ominous name.

Guessed classes

Candidate, PAC and party classifications are not in our extract of the register. Inferring them from committee names would be our judgement in a column that looks like a filing.

How this index is built

Population

Every committee with a record page in the 2026 cycle — 608 of them. The archive holds 3,341 committees across all cycles; earlier cycles gain pages as they are imported.

Identity

The PDC committee ID, never the name. Two committees sharing a name are two rows.

Amounts

Itemised contributions and expenditures summed from the reports. Unitemised small giving is on each committee’s page, stated separately, and is not in the raised column here.

Default order

Alphabetical. Every other order is available and none is the default, because the default is the site’s opinion about what matters.
